Sjeng 2.7 released

[Tony Thomas]

By the way, we shall see if the new version lives up to the claims.

They have Ryb on their HDD which turns them instantly into Gods ...

[Dr.Wael Deeb]

I wonder how people come to the conclusion that it isnt grandmaster strength by playing two games against the strongest ever free engine.

I agree here Tony,it's not a correct approach....

[AdminX]

Played two quick Blitzgames on my A64 X2. Not exactly above Super Grandmaster level and not very humanlike either...

I played three games versus Hiarcs 11.2sp and did not find it's play bad at all. In fact I thought it was human like. Three games may not tell you alot about strength but you can get a idea about how well the engine plays in general. Fact is I don't care if it is the strongest engine out there or not, so long as it can play a good game of chess.

Hi,
What opening book did Rybka use in these games

She used a "One Variation book". 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qe6+, the so called Letterman-Variation of the Center Counter.

After the further moves 4.Be2 Qg6? (a bad move which is of course not in the book) we have this position:

[d]rnb1kbnr/ppp1pppp/6q1/8/8/2N5/PPPPBPPP/R1BQK1NR w KQkq - 0 5

Shredder crushed List in a game published by Kurt Utzinger in the old Forum and I use this position as testposition ever since.
I don't trust engines for opening or early middlegame Analysis if they don't want to play 5.Nf3 here.

Aha,I see,so it's a theme match after all....
Thanks for the reply

[Werner]

, I mean Deep Sjeng 2.7, has its evaluation function entirely automatically learned from watching Grandmaster games.

does this mean, DeepSjeng27 is tuned against a special chess engine too?
Which one ?

[chessfurby]

Werner as said above:
Eval learned from a grandmaster database (human gms). It was a first experiment with which GCP was happy.

So there is no talk about engine here ...

[Dr.Wael Deeb]

To quote GCP (whose ccc account is not working atm):


Hi all,

Deep Sjeng 2.7 was just released. For people who have bought Deep Sjeng 2.5 this is a free update. Just install Deep Sjeng 2.7 and your code for Deep Sjeng 2.5 will still work.

For the silly people who have not bought it yet we offer a free 30-day trial just like the previous time

http://www.sjeng.org/deepsjeng2

Noteworthy new features:
* Engine +/- 50 ELO stronger than Deep Sjeng 2.5
* *Vastly* improved passed pawn and kingsafety understanding
* SMP improvements
* Adjustable board graphics, GUI usability tweaks
* GUI supports pondering
* Improved analysis options in GUI
* Opening book now a lot bigger

The new engine is actually an improved version of "Stoofvlees" who played in the last Leiden tournament. "Stoofvlees", err, I mean Deep Sjeng 2.7, has its evaluation function entirely automatically learned from watching Grandmaster games. Aside from making my job a lot easier (no more tuning to do at all!), the engine has noticeably improved in strength, particularly in the areas where it was less optimal before. Passed pawn handling is simply on another level compared to Deep Sjeng 2.5. There is also a strong effect on the playing style which will be easily noticeable: the engine plays very humanlike, which isn't surprising, given that it learned chess from watching GM's!

Overall I'm very happy with the result of this experiment, and it will be quite interesting to see how much further it can be taken...



www.sjeng.org

Cheers

Well,insulting people won't make your pocket thicker....
And again,I might remain silly after I took a look here for example:

Yes correct,
but I have 2 interesting results here:

Code: Select all

1   Deep Sjeng 2.7 2CPU  +22/-11/=17 61.00   30.5/50
2   Fritz 10             +11/-22/=17 39.00   19.5/50

Code: Select all

1   Shredder 10          +16/-14/=20 52.00   26.0/50
2   Deep Sjeng 2.7 2CPU  +14/-16/=20 48.00   24.0/50

In our list Fritz 10 and Shredder 10 are nearly equal strong.

Congrats to that good results!
